"As we speak, a fleet of one hundred twenty-six ships, seventy-five of them capital ships, is investing Sluis Van to block any reinforcements from that sector. I am at this very moment landing a force of fifty thousand battle droids on Praesitlyn in a feint to divert the garrison from the Intergalactic Communications Center. When that operation is fully under way, I will land the main force, composed of, give or take, a million battle droids, crush the defenders in a containment maneuver, and capture the center intact. I have two hundred ships in my invasion fleet. This operation cannot possibly fail. I guarantee you that within twenty-four standard hours of the commencement of Operation Case White, Praesitlyn will be ours. We will sit firmly astride the communications link that connects the worlds of the Republic. Our forces will be poised at this strategic crossroads to strike without warning at any of the Republic's allies. Most important, our control of Praesitlyn will be a vibroblade thrust directly at Coruscant itself. This is the move that will win the war for us. They'll never know what hit them, those technicians down there and their security forces. They'll soon all be dead-or be assets belonging to us."

At some point during the Clone Wars, the Republic recaptured Praesitlyn. As the planet had few defenses, the Republic considered to dispatch reinforcements from the nearby Sluis Van Shipyards. Nevertheless, the Separatists responded by a major offensive against Praesitlyn, combined with the blockade of Sluis Van.[6] Due to the intense fightings at Praesitlyn and the neighboring systems during the war, one of the main theaters of the Outer Rim Sieges was named after the planet.[9]
